Actually both Patty and Patsy were in frequent use as female names in the USA centuries before Patricia was in use. In the 1600s and 1700s these were pet forms of Martha, just as Peggy was a pet form of Margaret and Polly was a pet form of Mary. [noted -ed]

Patty is such an unpleasant name. It conjures up images of an overweight, unattractive older woman who is either sinister or is overly sweet and easily becomes oblivious to everything around her. The name itself, Patty, is hideous as well.

There are two Peanuts characters named Patty: Patty, who debuted in the very first Peanuts strip on October 2, 1950 (I like to call her "Bow Patty" because of the bow in her hair), and Peppermint Patty, who debuted in the strip on August 22, 1966.
